hi...first let me know ...do you have been reinstalling new operating system (OS) to this laptop...if the answer yes..make sure u not forget to install driver for your laptop completly....and make sure that drivers is compatible with your OS.
second...do you any problem before with this device?...if not check the default setting of the device...check via control panel...audio and device....make it turn on as factory setting...but if yes have ever check with another mic...if still happened you must take your laptop to acer nearset service center...that mean you have problem with hardware on your laptop
My laptop model is compaq presario c754tu, I have installed Windows Vista Business, and the audio is working fine, but the internal mic and external microphone both work together........i want to mute the internal mic..... how i can do it ? please reply me on my email id i.e. email@example.com
Hi please check the audio properties settings of your system . The MIC would have been MUTED . Uncheck the mute against mic and you should be able to record thru the built-in mic.Right click on speaker icon in taskbar audio properties under mic uncheck in the box beside mute.
OK ya have a bad connection problem, I think the wires that go between the case and screen may be damaged or loose? in any event ya gonna haveta take it to a repair shop :( The Mic problem MAY be inter-related.. however until ya fix the screen this is a moot point, no? The Mic problem is probably just an incompatibility problem... not aLL mic's work on all pc's even when they work on others.. Oh say try a USB mic they are great.
assuming that the mic itself isnt faulty, go to the right side of your taskbar and right click on the grey spekaer, not the red one and click on recording devices.
When the window pops up make sure the mic realtek HD audio has a green tick and not the line in icon, next click properties and check the settings,you can also configure the mic from this window.
